Twin benefits

John Eoin Douglas (Letters, 9 November) suggests that we “twin” with Amsterdam because it also has problems with its tram system. It might be even better to liaise with countries that have built a tram system successfully. When Melbourne can build 3km of tramline for £13.5 million, we may have something to learn.

Further, China can build a mile of road for £840,000, despite alleged corruption there, but Scotland’s Aberdeen bypass is £23.3 million a mile. Perhaps Alex Salmond could “twin” with its government to our benefit.
